Pharmaceutical composition including dead cells of lactobacillus acidophilus lb to treat or prevent allergic disease

ABSTRACT

Provided is a pharmaceutical composition including dead cells of  Lactobacillus acidophilus  LB strain as an active ingredient for treating or preventing an allergic disease, and may be used to treat and prevent IgE-mediated allergic diseases and non-IgE-mediated allergic diseases such as atopic dermatitis, allergic rhinitis, allergic conjunctivitis, urticaria, and pollinosis by reducing the total content of IgE in the blood.

TECHNICAL FIELD

The present invention relates to a pharmaceutical composition for treating or preventing an allergic disease, and particularly, a pharmaceutical composition for treating or preventing an allergic disease, which includes dead cells of Lactobacillus acidophilus LB as an active ingredient.

BACKGROUND ART

It is known that allergic diseases are largely divided into immunoglobulin (IgE)-mediated diseases and non-IgE-mediated diseases. It is known that when allergens triggering an allergic disease are penetrated into a body, the allergic disease is triggered and worsened by imbalance of Th(helper)1/Th(helper)2 lymphocytes.

In addition, it is known that abnormal differentiation of Th2-cells is induced by action of a cytokine including IL-4 (according to the recent study, when production of IL-4 and IL-5 are reduced, an allergic disease is not improved, and thus IL-4 and IL-5 are also known as unimportant factors in triggering of the allergic disease), cytokines including IL-9, IL-33, and thymic stromal lymphopoietin (TSLP), regulatory T-cell (Treg) families (nTreg, Th3, and iTreg), and newly known effecter cells such as nuocytes, Th9, and Th22, which induce Th2 differentiation.

When microorganisms or chemicals and allergens are penetrated, rather than that TSLP, as a primary inducer of Th2 immune deviation, is produced by epitheliums in the skin, intestines, and lung to stimulate dendritic cells, thereby stimulating production of Th-2 cytokine and directly producing cytokines, a TSLP-primed dendritic cells (DCs) serve to up-regulate costimulatory molecules (molecules of antigen presenting cells) and increase production of Th2-attracting chemokines including thymus and activation-regulated chemokine (CCL17), macrophage-derived chemokine (CCL22), IL-15, and IL-18. Similarly, in the skin, TSLP expression provokes atopic dermatitis.

Meanwhile, large amounts of keratinocytes are expressed in atopic dermatitis patients. That is, an allergen induces amplification of TSLP-mediated Th2 response. When production of IL-25 is increased by an allergen, production of CCL5 (RANTES) and CCL11 (eotaxin-1) is increased, and thus eosinophils remain at a part in which inflammation occurs. In addition, interleukin-33 (IL-33) secreted from necrotized cells generated by reaction to infection and inflammation is expressed in bronchial epithelium, fibroblast, keratinocytes, smooth muscle cells, dendritic cells, mast cells, and macrophages, and serves as a chemoattractant to Th2 cells, in addition to Th2 immune deviation. When IL-33 is administered, Th2 immune deviation, cytokine production, elevated IgE, and mucosal eosinophilic inflammation are induced to cause DC differentiation, thereby inducing expression of major histocompatibility complex class 2, CD86, and IL-6. The activated DC as described above stimulates differentiation of naive CD4+T cells to increase production of IL-5 and IL-13, and IL-33 helps in maturation of a CD34+ mast cell precursor and homing to a tissue. As a result, activation of IL-25, IL-33, and TSLP that are imbalanced in inducing and worsening an allergic disease results in allergic diseases through a pathological and inflammatory process of allergic diseases due to activation of cells inducing and worsening the allergic diseases such as Th cells, mast cells, DCs, eosinophils, and basophils.

As the allergic diseases, atopic dermatitis, allergic rhinitis, allergic conjunctivitis, rash, pollinosis, or asthma is known.

It is reported that atopic dermatitis is expressed 50% at the age of 1, and 80% at the age of 5, and usually is shown as a chronic, relapsing skin disease, for example, eczema on the folds of a body such as antecubital fossa or popliteal fossa. Usually, IgE is increased in a serum, and allergic rhinitis and asthma are accompanied as a person grows. Prevalence in the developed countries varies depending on a reporter in a range from 20 to 30%, and it is reported that in Korea, prevalence is 10% at the age of 6 or less, 6% at the age of 6 to 12, and generally 2% at the age of 20 or more. The atopic dermatitis is classified into an intrinsic type or an extrinsic type according to a clinical phenotype, and depending on a reporter, the prevalence of the intrinsic dermatitis varies in the range of 10 to 30.4%, and clinical characteristics of the intrinsic dermatitis determined by a skin prick test are normal in total IgE level in serum, negative in allergy-inducing food, and negative in allergen-specific serum IgE with respect to general aeroallergens and food allergens. The extrinsic atopic dermatitis has the highest frequency at the age of 18 or more, averagely 31.6, and the intrinsic atopic dermatitis has the highest frequency at the average age of 27.1. The average age of total patients with intrinsic dermatitis is 30.4, and it is reported that the frequency is considerably reduced according to time, and the intrinsic dermatitis barely occurs over 57 or more years old. In addition, it was reported that 57.8% of patients with atopic dermatitis was accompanied with allergic conjunctivitis or asthma, 61.7% of the patients were increased in total IgE, 26.5% of the patients had a total IgE of 300 IU/ml or more, and 36.7% of the patients had 1^(st)-degree relatives.

In addition, allergic rhinitis is a symptomatic disorder of the nose inducing an IgE-mediated inflammation after allergen exposure, and causing symptoms in a nose, eyes, ears, and fauces. Previously, it was classified into seasonal or perennial allergic rhinitis, but presently is divided into intermittent allergic rhinitis or persistent allergic rhinitis, and subdivided into mild, moderate, or severe allergic rhinitis based on duration of symptoms by “the Allergic Rhinitis and Its Impact on Asthma Working Group.” The prevalence is 10 to 30% in adults, and approximately 40% in children, which are a bit different according to a reporter in each country. Allergic rhinitis risk factors are indoor and outdoor allergens and when serum IgE is 100 IU/ml or more before the age of 6. Allergic rhinitis develops complications such as sinusitis, otitis media, conjunctivitis, and sleep disturbance, an attention problem, and maladjustment of a social life due to exacerbation of asthma and sinusitis when not treated and thus becoming worse.

In addition, urticaria is a disease temporarily expressing well-circumscribed wheals in red or white on a superficial portion of dermis and mucosa. When the symptoms do not persist 6 weeks, it is defined as acute urticaria, and when persisting over 6 weeks, it is defined as chronic urticaria. The urticaria is caused by internal and external factors, and mostly foods, drugs, food additives, and infectious and physical stimuli (cold, heat, exercise, solar rays, and mechanical irritation) are estimated as main causes. Inhalants such as pollen, animal dander or fur, spores of fungi, house dust mites, air sprays, etc. are inhaled through respiration to cause urticaria, and foods are generally causes of acute urticaria, but barely induce chronic urticaria. As foods that frequently cause urticaria, chocolates, clams (particularly, Meretrix lusoria), peanuts, peas, chestnuts, tomatoes, kiwis, egg whites, cheeses, garlic, onions, and food additives [yeast, salicylic acid, citric acid, azo dyes, or benzoic acid derivatives] are used, and as drugs, various drugs such as aspirin, sulfone amide, narcotic, NSAID, vitamin, estrogen, insulin, quinine, salicylate, etc. are used. The urticaria is easily diagnosed only by clinical symptoms, and if it is difficult to find a cause, various examinations may be helpful to find the cause. For treatment, avoidance after finding a cause is ideal, but since it is difficult to find a cause, various public remedies are performed.

To treat such an allergic disease, various therapies are being studied, and anti-allergic agents, histamine receptor antagonists (antihistamines), steroids, etc. are used. However, any one of an antihistamine inhibiting signal transduction from peripheral nerves by being linked with a histamine receptor antagonistically to histamine, an anti-allergic agent reducing an activity of chemical mediator-producing cells to attempt alleviation of symptoms, and a steroid reducing immune responses to alleviate inflammation has side effects, but there is no dramatic effect.

Meanwhile, lactobacilli is a product first found by Metchnikoff and obtained from attempts to obtain a therapeutic effect by acidifying intestinal contents to prevent growth of putrefactive organisms, and 165 species of Lactobacillus genera considered as representative lactobacilli are found. Particularly, as a probiotic lactobacillus which has been used in treatment of an allergic disease, it has been reported that Lactobacillus acidophilus L-92 has effects on some of allergic rhinitis symptoms triggered by Himalayan cedar pollens in Japan, and use of Lactobacillus rhamnosus GG, Lactobacillus acidophilus species, Lactobacillus reuteri species, Lactobacillus fermentum species, Bifidobacterium breve species, or Bifidobacterium lactis species has been attempted to treat atopic dermatitis.

As Lactobacillus acidophilus species strains separated from a human intestine among the strains of the Lactobacillus genera, strains clinically used for treatment such as Lactobacillus acidophilus LB strain, Lactobacillus acidophilus 145 strain, Lactobacillus acidophilus DDS-I strain, Lactobacillus acidophilus L-92 strain, Lactobacillus acidophilus NCFM strain, Lactobacillus acidophilus LA 02 strain, Lactobacillus acidophilus L-55 strain, Lactobacillus acidophilus NCK56 strain, Lactobacillus acidophilus CH5 strain, Lactobacillus acidophilus LAFTIL-10 strain, Lactobacillus acidophilus OLL2769 strain, and Lactobacillus acidophilus 27L strain were used. Among these, only two kinds of the strains such as Lactobacillus acidophilus DDS-1 strain and Lactobacillus acidophilus NCFM strain were used in treatment of an allergic disease, but an effect on treating or improving an allergic disease was not proved.

Meanwhile, Lacteol is a product name of a freeze-dried product of a culture solution containing tyndallized dead cells of Lactobacillus acidophilus LB strain found by the French doctor, Pierre BOUCARD, in 1907, and a dead cell drug conserving a metabolite produced by Lactobacillus acidophilus LB strain, which is known as a safe drug having no fatal side effects since it was produced in 1979 and no fatal reports with long-term use, is known to be effective in acute diarrhea and diarrhea caused by colitis and functional colonic diseases, but it was never used in treatment of an allergic disease.

The inventor found that Lacteol containing dead cells of Lactobacillus acidophilus LB strain had excellent therapeutic effects and improvements in symptom, compared to the primary therapeutic agents of atopic dermatitis, calcineurin inhibitors, a therapeutic agent to allergic rhinitis, antihistamines, and intranasal inhalants, and therefore the present invention was completed.

MODES OF INVENTION

The present invention provides a pharmaceutical composition for treating or preventing an allergic disease containing dead cells of Lactobacillus acidophilus LB strain as an active ingredient.

The Lactobacillus acidophilus LB strain of the present invention is isolated from human feces, and registered under MA65/4E to French National Collection of the Pasteur Institute (CNCM).

The dead cells of the Lactobacillus acidophilus LB strain of the present invention are cells killed by thermal treatment, and normally prepared by heating live cells at 70 to 90° C. higher than a dry temperature. Preferably, the dead cells of the present invention are a culture solution containing dead cells obtained by repeatedly heating cells by intermittent thermal treatment called tyndallization. For example, the dead cells may be prepared by freeze-drying a culture solution containing dead cells prepared by inoculating and culturing LB strains in whey broth at 37° C. for 3 days and heating the broth at 75° C. for 15 minutes a day, thereby killing spores.

The term “contained as an active ingredient” used herein means that dead cells of the Lactobacillus acidophilus LB strain are contained in a sufficient amount to achieve a treating or preventing effect on an allergic disease. In one exemplary embodiment of the present invention, a content of dead cells of the Lactobacillus acidophilus LB strain is 100 million or more cells/g, preferably 1 to 10 billion cells/g in the pharmaceutical composition of the present invention. The dead cells of the Lactobacillus acidophilus LB strain of the present invention has no specific side effect on a human, except loose feces, and thus a quantitative upper limit of the dead cells of the Lactobacillus acidophilus LB strain included in the pharmaceutical composition of the present invention may be selected within a suitable range by one of ordinary skill in the art.

The pharmaceutical composition of the present invention may be orally administered, and a suitable dosage of the pharmaceutical composition of the present invention varies according to factors such as a formulation method, an administration method, age, body weight, sex, a diseased condition of a patient, food, administration time, an administration route, an excretion speed, and reaction sensitivity, and ordinarily trained doctors can easily determine and prescribe a dosage effective in desired treatment or prevention. According to an exemplary embodiment of the present invention, a daily dosage of the pharmaceutical composition of the present invention is 1 to 10 billion, preferably, 5 to 8 billion dead cells based on an adult for oral administration. In infants or younger children, based on a body weight ranging from 20 to 40 kg, approximately ½ of the adult dosage may be administered, and based on a body weight of less than 20 kg, approximately ¼ of the adult dosage may be administered. The pharmaceutical composition of the present invention may be administered at the daily dosage once to twice a day.

The pharmaceutical composition of the present invention may be formulated using a pharmaceutically available carrier and/or excipient, and prepared in a unit capacity or contained in a high-dosage container according to a method that can be easily executed by one of ordinary skill in the art. Here, a dosage form may be a tablet, a capsule, a granule, powder, or liquids such as an aqueous medium-containing solution, a suspension, or an emulsion.

For example, to formulate the pharmaceutical composition in the form of a tablet or capsule, the active ingredient may bind to an oral, non-toxic pharmaceutically available inactive carrier such as ethanol, glycerol, water, etc. In addition, when desired or needed, a suitable binding agent, lubricant, disintegrating agent, coloring agent, or a mixture thereof may be included. The suitable binding agent may be, but is not limited to, natural sugar such as starch, gelatin, glucose, or beta-lactose, a natural or synthetic gum such as corn sweetener, acacia, Tragacanth, or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, or sodium chloride. The disintegrating agent includes, but is not limited to, starch, methyl cellulose, agar, bentonite, or xanthan gum.

As pharmaceutically available carriers for the composition prepared in a liquid, those suitable for sterilization and a living body, a saline, sterilized water, a Ringer's solution, a buffered saline, an albumin injection, a dextrose solution, a maltodextrin solution, a glycerol, ethanol, or a mixture of at least one thereof may be used, and conventional additives such as antioxidants, buffers, bacteriostats, etc. may be added when needed.

Furthermore, as a suitable method used in a corresponding art, using a method disclosed in Remington's Pharmaceutical Science, Mack Publishing Company, Easton Pa., the pharmaceutical composition is preferably formulated according to a disease or component.

The pharmaceutical composition of the present invention reduces a total IgE content in the blood by oral administration. Accordingly, the pharmaceutical composition of the present invention may be used in treatment and prevention of an IgE-mediated allergic disease and a non-IgE-mediated allergic disease, for example, atopic dermatitis, allergic rhinitis, allergic conjunctivitis, urticaria, and pollinosis.

The present invention is not limited to cases that will be described below, but will be realized in various different types. The cases are merely provided to completely describe the scope of the present invention to those of ordinary skill in the art, and the present invention is only defined by the scope of the claim.

In a clinical trial of the present invention, as a culture solution containing tyndallized dead cells of Lactobacillus acidophilus LB strain, Lacteol (tablet) produced by Lacteol in France, and purchased from Dongwha Pharm. Co. Ltd was used. One tablet of Lacteol (1 tablet/g) includes 2.5 billion tyndallized dead cells of Lactobacillus acidophilus and has an apparent effect in diarrhea, and thus 4 to 8 tablets are recommended daily to an adult with acute diarrhea or irritable bowel syndrome having a primary symptom of diarrhea.

However, the fact that Lacteol affects an allergic disease, and a dosage of Lacteol have not been known. The inventor confirmed whether Lacteol had therapeutic effects on an allergic disease when at a low dosage of approximately ½ to ¼ the dosage for acute diarrhea: 2 tablets daily in adults, 1 tablet daily in older children having a body weight of 20 to 40 kg, and a ¼ tablet daily in younger children or infants having a body weight of less than 20 kg.

Clinical trials were carried out in a total of 34 patients with allergic diseases at the age ranging from 3 to 70, and a follow-up was performed for averagely 1 to 2 months since Lacteol had been administered.

Many scales to assess a clinical progress and therapeutic effects for atopic dermatitis are reported. Representatively, there are Eczema Area and Severity Index (EAST), SCORing Atopic Dermatitis (SCORAD), Patient Oriented Eczema Measure (POEM), and Three Item Severity (TIS). In the clinical trial, the TIS scale widely known as a prescreening system or quick system was used. The TIS scale consists of three items: erythema (redness), edema, and excoriation (scratches), and each item is graded on a scale 0 to 3 points: 0 point represents no change, 1 point represents mild, 2 points represent medium, and 3 points represent severe intensity, and the maximum point is 9. Severity of atopic dermatitis scored by the TIS scale is classified into a mild form (0 to 2 points), a moderate form (3 to 5 points), or a severe form (6 to 9 points) [Practical issues on interpretation of scoring atopic dermatitis: the SCORAD index, objective SCORAD, and the three-item severity score-review article].

In addition, allergic rhinitis is an indicator for a clinical process and a therapeutic effect, and various scales are known, and in clinical cases provided herein, a symptom scale (SS) was used among various scales applied to “Using the Congestion Quantifier Seven-Item Test to Assess Change in Patient Symptoms and Their Impact” disclosed in Allergy Asthma Proc 29:295-303, 2008. The SS consists of nine items, including four primary symptoms of allergic rhinitis and five symptoms accompanied with allergic rhinitis. For example, rhinitis symptoms consisting of nasal discharge, nasal congestion/stuffiness, nasal itching, and sneezing; and non-rhinitis symptoms consisting of itching/burning eyes, tearing/watering eyes, redness of eyes, itching of ears or palate and cough, and severity is rated on a 4-point scale: 0=none; 1=mild; 2=moderate; and 3=severe. Total SS is given by summarizing scores of the nine items.

Other than the above-described nine items, urticaria and acne, skin whitening and improvement were determined by photographs and with the naked eye.

Hereinafter, 34 cases will be described in detail, real names of patients except their last names were removed, males were described as M and females were described as F, and the age was shown behind the sex.

Total IgE was carried out in adult patients consenting to blood-gathering among patients with severe atopic dermatitis or allergic rhinitis, and lesions before and after treatment in all of the 34 patients were photographed to compare and stored as supporting evidences. Among the photographs, by comparing only the photographs of the patients in the cases 1, 9, 18 and 25 before and after treatment, a degree of improvement was easily identified, and then the photographs were attached to the specification as drawings.

Case 1) Jung 00 (f/26)

Over 20 years, the patient had been suffering from severe atopic dermatitis, and visited the hospital on Sep. 6, 2011. At the visit, severe edema, erythema, and excoriation were shown on the neck, antecubital fossa, popliteal fossa, etc., the TIS score of atopic dermatitis was 9, and total IgE was checked at 5326 IU/ml, which seemed very high.

Two tablets of Lacteol daily were administered, the total IgE measured at the second visit on October 5 was greatly reduced to 3906.7 IU/ml, and atopic lesions were graded as erythema (1 to 2 points), edema (1 to 2 points), and excoriation (1 to 2 points) by TIS as confirmed in photographs of legs before and after treatment in FIG. 1 and photographs of arms before and after treatment in FIG. 2, which indicated that atopic lesions had a mean TIS score of approximately 4 to 5 points, and were considerably improved to moderate lesions within one month of treatment.

At the third visit on November 10, a little erythema remained on the popliteal fossa and the frontal neck, and total TIS of all of the lesions were further improved to milder lesions having a score of approximately 1 to 2 points. At the third visit, the lesions became more apparently improved, and there was no side effect during the administration of Lacteol.

Case 2) Kim 00 (m/49)

The patient visited the hospital on Aug. 23, 2011 for weight loss and thirst, while suffering from severe pruritus caused by atopic dermatitis for 10 or more years, particularly, severe erythema, scratching, and severe itching on both shins, and nasal stuffiness (3 points), sneezing (2 points), and nasal discharge (2 points) caused by allergic rhinitis. At the visit, total IgE carried out under the doubt of diabetes (HbAlC-13.6) and atopy was measured at 544.6 IU/ml, atopic dermatitis on the both shins was graded as erythema (3 points), edema (1 point) and excoriation (2 to 3 points) by TIS, and atopic dermatitis on the right side of the face were graded as erythema (2 to 3 points) and edema (1 to 2 points) by TIS.

Combining with diabetes treatment, two tablets of Lacteol were administered daily, total IgE carried out at the second visit on September 26 was reduced to 300.6 IU/ml, atopic dermatitis triggered mild erythema, edema, and scratching on both shins, graded as 0 to 1 point by TIS, and erythema and edema on the face area were greatly decreased and became brighter. Pruritus all over the body was so improved that it was barely noticed, and during the administration of Lacteol, there was no specific side effect.

Case 3) Song 00 (m/52)

The patient visited the hospital on August 8 for cough. Total IgE carried out under the doubt of asthma and allergic rhinitis was checked at 957.1 IU/ml, and the patient had severe pruritus, and allergic rhinitis accompanied with symptoms including nasal stuffiness (3 points), nasal discharge (2 points), sneezing (2 points), and nasal itching (3 points) for 3 to 4 years. In addition, the rhinitis symptoms had total SS of 10 points, which were severe.

Two tablets of Lacteol were prescribed daily, and total IgE carried out at the second visit on September 30 was reduced to 593.6 IU/ml, the allergic rhinitis symptoms including nasal stuffiness (1 point), nasal discharge (1 point), sneezing (1 point), and nasal itching (1 point) were reduced, resulting in showing mild severity. The whole body pruritus was highly improved and thus barely noticed, and there was no discomfort caused by the Lacteol administration until the time of the visit.

Case 4) Gu 00 (m/36)

The patient visited the hospital on Oct. 13, 2011 for urticaria distributed on the entire body whenever he sweated for approximately 3 years. Total IgE carried out at the visit was a bit increased to 91.6, and overall, 2 to 3 mm small wheals were distributed on large erythematous redness.

Two tablets of Lacteol were prescribed daily, and since total IgE was low at the first visit, it was not measured at the second visit on November 9, and as therapeutic effects on cholinergic urticarial lesions, erythematous redness and small wheals were notably decreased on his back, left side of the face, and left antecubital fossa. In addition, pruritus became also alleviated, and there was no side effect at the visit.

Case 5) Yu 00 (f/50)

The patient visited the hospital on Sep. 19, 2011, while treated and taking a drug in an ophthalmology clinic for allergic conjunctivitis 1 week ago because of uncured allergic rhinitis and conjunctivitis suffering for approximately 12 years. At the visit, according to SS, allergic rhinitis was graded as nasal stuffiness (3 points), nasal discharge (2 points), nasal itching (3 points), eye redness (2 to 3 points), eye itching (3 points), and eye tearing (2 points). Since she took an antihistamine before coming to the hospital, total IgE was 409.2 IU/ml, which was otherwise considered higher.

Two tablets of Lacteol were administered daily, and at the second visit on November 8, total IgE was reduced to 313.2 IU/ml, and according to SS, allergic rhinitis were considerably improved to be mild severity and graded as nasal stuffiness (1 point), nasal discharge (1 point), nasal itching (1 point), eye redness (0 point), eye itching (0 to 1 point), and eye tearing (1 point), and eye redness and whitish scaly erythematous redness on the left neck and the frontal area were likely to be highly improved, and there were no specific side effects during treatment.

Case 6) Jung 00 (m/10)

The patient was a son of Yu 00 (F/50) of Case 5) and visited the hospital on September 28. While he had been treated in a dermatology clinic, at the visit, he had lesions on the left popliteal fossa, graded as erythema (2 points), edema (2 points), and excoriation (1 to 2 points) by TIS.

Since his body weight was less than 40 kg, one tablet of Lacteol daily was prescribed. The lesions seemed to be considerably improved and graded as erythema (0 to 1 point), edema (0 point), and excoriation (1 point) by TIS carried out at the second visit on November 9, and there was no side effect.

Case 7) Oh 00 (m/53)

The patient visited the hospital on Sep. 16, 2011 while treated in a dermatology clinic for atopic dermatitis and pruritus. At the visit, total IgE was 471.9 IU/ml, and lesions were on the back of the right and left ears, and around the chins, and graded as erythema (1 to 2 points), edema (1 to 2 points), and excoriation (1 point) by TIS.

Two tablets of Lacteol daily were prescribed, and total IgE carried out at the second visit on November 4 was a little reduced to 450.6 IU/ml. It was determined that the fact that the total IgE was relatively lower than those of other patients was because the total IgE was already decreased at the first visit due to administration of a drug prescribed in the dermatology clinic. At the second visit, the lesions were considerably improved and graded as erythema (0 to 1 point), edema (0 point), and excoriation (0 point) by TIS, and there was no specific side effect.

Case 8) Kim 00 (f/50)

The patient visited the hospital on Aug. 27, 2011 for atopic dermatitis over 10 years. Total IgE carried out at the visit was 14.4 IU/ml, which was in the normal range. Since she continuously administered antihistamine prescribed in a dermatology clinic, it was not known whether the atopic dermatitis was or was not intrinsic atopic dermatitis, and lesions on elbows and right antecubital fossa, etc. were graded as erythema (2 to 3 points), edema (2 to 3 points), and excoriation (2 to 3 point) by TIS.

Two tablets of Lacteol were administered daily, and at the second visit on November 5, almost all of the lesions disappeared, and there was no side effect.

Case 9) Cho 0 (m/28)

The patient had been taking various treatments for atopic dermatitis since childhood, but not considerably improved, and thus stopped treatment for a while, but visited the hospital on Aug. 8, 2011. At the visit, he had severe atopic dermatitis all over the body, and particularly, on his back and neck, graded as erythema (3 points), edema (3 points), and excoriation (3 points) by TIS, and lots of pustular papules [refer to FIG. 3( a)].

Two tablets of Lacteol daily were prescribed, but the patient intermittently administered and daily administered two weeks before the visit on October 29. At the second visit, symptoms were milder, and graded as erythema (1 to 2 point), redness (0 to 1 point), and excoriation (2 points) by TIS, and many pustular papules disappeared [refer to FIG. 3( b)].

For a more rapid effect, three tablets of Lacteol were administered daily, and visited the hospital again after 11 days on November 9. He showed improved symptoms graded as erythema (0 to 1 point), edema (0 to 1 point), and excoriation (1 to 2 points) by TIS. There was no side effect regardless of a dose.

Case 10) Cha 00 (f/41)

The patient visited the hospital on Aug. 30, 2011 for lots of erythematous pustular papules (acne) on her face.

Two tablets of Lacteol were administered daily, and at the second visit on October 18, her skin looked clearer and brighter, and lots of lesions disappeared, and there was no side effect.

Case 11) Ok 00 (m/5)

The patient had been suffering from atopic dermatitis for three years, and visited the hospital on Sep. 28, 2011. At the visit, atopic dermatitis was graded as erythema (1 to 2 points), edema (1 point), and excoriation (1 to 2 points) by TIS, and shown on the frontal chest area, and the left side of and behind the neck.

Since his body weight was less than 20 kg, ½ tablet of Lacteol daily was administered. At the second visit on October 22, the symptoms were improved and graded as erythema (0 to 1 point), edema (0 to 1 point), and excoriation (0 to 1 point) by TIS, and there was no discomfort and side effect during administration.

Results of Clinical Trials

1) Considerable Decrease in Total IgE

Total IgE before and after treatment was measured in 22 adult patients consenting to blood gathering among 34 patients with severe atopic dermatitis or allergic rhinitis to demonstrate therapeutic effects.

Among the 22 patients, in the patients in Cases 4 and 8 that had the total IgE value was 91 IU/ml or less, which was the same as the value of a normal adult, the measurement of total IgE was not applied thereto, and changes in total IgE were examined in the rest of the patients except the patients in Cases 7, 15, 16, and 22 to which antihistamines, steroid ointments, etc. were used to improve allergic diseases before treatment.

First, FIG. 7 shows the change in total IgE before and after treatment in the patient with a very severe allergic disease having a value of total IgE before treatment of 900 IU/ml or more, and FIG. 8 shows changes in total IgE before and after treatment in other patients. In all of the patients in FIGS. 7 and 8, total IgE values were considerably decreased after treatment, and thus it was confirmed that Lacteol was effective in treating an IgE-mediated allergic disease.

2) Decrease in TIS Scales of Patients with Atopic Dermatitis

Among the 34 patients, the number of patients with atopic dermatitis was 23, and values of the TIS scale before and after treatment were compared. The results are listed in Table 1.

TABLE 1 Case No. Before treatment After treatment 1 9 4.5 2 6.5 1.5 6 5.5 1.5 7 4 0.5 8 7.5 0.5 9 9 4 11 4 1.5 12 7 1.5 13 4.5 1.5 14 5.5 1.5 15 7 3 16 5.5 1 17 4 1 18 7.5 2 19 5 1 23 4.5 1.5 24 6 2 25 9 3 26 7.5 1.5 29 5.5 1.5 30 5.5 1.5 33 4.5 0.5 34 5.5 1.5

It was confirmed that, in the patients with severe atopic dermatitis of a mean severity of 6.1 before treatment, after 1 to 2-month treatment, atopic dermatitis was considerably improved to a mild form having a severity of 1.7.

3) Decrease in SS Scales of Patients with Allergic Rhinitis

Among the 34 patients, the number of patients with allergic rhinitis was 16, and values of the SS scale before and after treatment were compared. The results are listed in Table 2.

TABLE 2 Case No. Before treatment After treatment 2 7 0 3 10 4 5 15.5 5.5 13 9.5 3.5 19 10 4 20 11 5 21 12.5 4.5 22 17.5 7.5 23 8.5 4.5 24 7.5 3 25 14.5 6 27 13 4.5 28 12 6 31 9.5 4.5 32 15 6.5 33 8.5 4

It was confirmed that severities of the patients with allergic rhinitis were considerably improved to 4.6 after treatment from averagely 11.3 before treatment.

4) Other Improved Effects

In addition to the atopic dermatitis and allergic rhinitis, in the patients of Cases 4 and 14, urticaria was improved, in the patients of Cases 5, 21, 22, and 27, improvement in allergic conjunctivitis was confirmed, and in the patients of Cases 10, 16, 24, and 28, improvement in acne was confirmed.

5) Side Effects There was no case reporting noticeable side effects such as constipation and abdominal distention during the treatment of the 34 patients. However, in the three-year-old infant of Case 12, when ½ tablet of Lacteol was administered daily, loose stool was shown, and thus a dosage was reduced to a ¼ tablet.
